SEERAM RAMAKRISHNA 아시아기술혁신학회 2015 Asian Journal of Innovation and Policy Vol.4 No.3

Universities are now operating in a post-globalized world. They need to be locally engaged while globally visible for continued success. Specific strategies include 1) unbundling education using fractal modules approach to facilitate more flexible and customized learning expectations of net generation of students; 2) open-source software and hardware platforms to facilitate collaborations around a short or multi-year, multidisciplinary brain stretching projects motivated by the real world challenges; 3) new courses on innovation and entrepreneurship to nurture experience seeking and enterprising mindset of students; 4) cross-border university- public- private partnerships for developing solutions specific to the local needs and can be scalable for the world; and 5) encouraging faculty members with glocal mindset.

Is Asia a choice for careers in Innovation?

SEERAM RAMAKRISHNA 아시아기술혁신학회 2012 Asian Journal of Innovation and Policy Vol.1 No.2

Asia is becoming a stronghold for innovation careers along with its resurgence in economic, political, and cultural arenas. This transformation happened on the backdrop of growing enrolments in higher education, increasing investments in scientific research & innovation, and innovation supportive policy measures by several Asian countries. Research and Development (R&D) and product customization centres of multinational corporations (MNCs) sited in emerging nations are also instrumental in this transformation.

As a special review article, several significant and applied results in 3D printing and additive manufacturing (AM) scienceand technology are reviewed and studied. Which, the reviewed research works were published in 2020. Then, we wouldhave another review article for 2021 and 2022. The main purpose is to collect new and applied research results as a usefulpackage for researchers. Nowadays, AM is an extremely discussed topic and subject in scientific and industrial societies, aswell as a new vision of the unknown modern world. Also, the future of AM materials is toward fundamental changes. Which,AM would be an ongoing new industrial revolution in the digital world. With parallel methods and similar technologies,considerable developments have been made in 4D in recent years. AM as a tool is related to the 4th industrial revolution. So,AM and 3D printing are moving towards the fifth industrial revolution. In addition, a study on AM is vital for generating thenext developments, which are beneficial for human beings and life. Thus, this article presents the brief, updated, and appliedmethods and results published in 2020.

<P><B>Abstract</B></P> <P>In this study, we report a simple approach based on the complexation of water soluble polymer with metal cations, for fabricating well defined polypyrrole (PPy)/ionic liquid (IL) nanoparticles (24–44 nm in diameter) by chemical oxidation polymerization. This procedure doesn’t require harsh environment such as temperature and pressure and the simple process offers a great possibility for mass production of polymer nanoparticles. The obtained PPy/IL nanoparticles were tested as an electrocatalyst for oxygen evolution reaction. We have not added any transition metal or metal oxide. But, the as-prepared catalyst has ionic liquid which containing 1-allyl-3-methylpyridinium cation and tetrachloronickelate anion complex. The as-prepared catalyst PPy/IL nanoparticles showed the Tafel slope of 53 mV dec<SUP>−1</SUP>. High catalytic activity of PPy/IL for OER is evident from low onset potential of 516 mV (η<SUB>1</SUB> = 328 mV) and high current density observed in the polarization curve. Moreover, the as-prepared catalyst achieved current density of 10 mA cm<SUP>−2</SUP> at low potential of only 583 mV which corresponds to an overpotential of only 392 mV.</P> <P><B>Highlights</B></P> <P> <UL> <LI> PPy/IL nanoparticles were synthesized via chemical oxidation polymerization. </LI> <LI> Tafel slope 55 mV dec<SUP>−1.</SUP> </LI> <LI> Low onset potential 516 mV (η<SUB>1</SUB> = 328 mV) observed at high current density. </LI> <LI> The catalyst showed remarkable stability and retained 83% of its initial activity. </LI> </UL> </P> <P><B>Graphical abstract</B></P> <P>[DISPLAY OMISSION]</P>

<P><B>Abstract</B></P> <P>Multiwalled carbon nanotubes/ionic liquid/Mn nanohybrids (MWCNTs/IL/Mn) are synthesized by chemical reduction method. This method involves functionalization of MWCNTs with pyridinium based dicationic ionic liquid and in situ reduction of MnCl<SUB>2</SUB>. The surface morphology of MWCNTs/IL/Mn nanohybrids analyzed by scanning electron microscopy (SEM) and transmission electron microscopy (TEM) showed the tubular structure of MWCNTs. It also revealed that Mn nanoparticles are distributed on the high surface area of MWCNTs/IL. The potential application of MWCNTs/IL/Mn as an electrode for supercapacitor devices is investigated using electrochemical methods. The cyclic voltammetry of nanohybrids electrode using 3.0M KOH electrolytes showed the presence of redox peaks suggesting pseudocapacitance behavior. The performance of the electrode is tested using cyclic voltammetry, galvanostatic charge-discharge and electrochemical impedance spectrometry. The as-prepared catalyst MWCNTs/IL/Mn nanohybrids electrode exhibit high specific capacitances of about 432.4 and 229.9Fg<SUP>−1</SUP> at scan rate of 5 and 10mVs<SUP>−1</SUP> respectively.

Facile strategy toward fabrication of highly responsive self-healing carbon/epoxy composites via incorporation of healing agents encapsulated in poly(methylmethacrylate) nanofiber shell

Rasoul Esmaeely Neisiany,Jeremy Kong Yoong Lee,Saied Nouri Khorasani,Rouhollah Bagheri,SEERAM RAMAKRISHNA 한국공업화학회 2018 Journal of Industrial and Engineering Chemistry Vol.59 No.-

Core–shell nanofibers encapsulating healing agents fabricated via the facile and economical coaxial electrospinning method, were incorporated in carbon fiber/epoxy composite panels to imbue them with self-healing ability. Two types of poly(methylmethacrylate) (PMMA) shell based nanofibers were fabricated, one with an epoxy resin core, the other with an amine-based curing agent core. The results indicated the incorporation of core–shell nanofibers containing healing agents not only improved the initial mechanical properties, but also resulted in self-healing carbon fiber-epoxy composites which were able to recover its initial mechanical properties up to four times after sustaining damage to failure.

<P>In the present review, we describe the development of a high energy density LIB fabricated with all 1D nanofibers as the anode and cathode, as well as a separator-cum-electrolyte prepared by an electrospinning technique without compromising the power capability and cycle life. Such a unique assembly certainly enables realizing the advantages of using 1D nanostructures in practical LIBs, irrespective of the anode or cathode in the presence of gelled polyvinylidene fluoride-<I>co</I>-hexafluoropropylene as the separator-cum-electrolyte. Outstanding cycling profiles with high power densities were noted for all the configurations evaluated. This excellent performance opens up new avenues for the development of high performance Li-ion power packs with a long cycle life and high energy and power densities to drive zero emission transportation applications in the near future, and opens up new research activities in this field as well.</P> <P>Graphic Abstract</P><P>The present review outlines high performance Li-ion cells fabricated with all one-dimensional materials as the cathode and anode, as well as a separator-cum-electrolyte prepared by an electrospinning technique. <IMG SRC='http://pubs.rsc.org/services/images/RSCpubs.ePlatform.Service.FreeContent.ImageService.svc/ImageService/image/GA?id=c4cc07824a'> </P>
